Episode 21 recap: Zhao Ruoqi was framed.

The national teacher took away the bracelet, and the celestial official was inside the bracelet, so he could see what was happening outside. The national teacher was very pleased, thinking that Zhao Ruoqi could become the virtuous concubine with the help of the celestial official. Now that he had taken the bracelet away, he wanted to see what Zhao Ruoqi could do. Both the eldest princess and the second princess were present when the second princess suddenly took out a knife and stabbed the eldest princess.

The eldest princess was also very surprised, thinking that the second princess wanted to provoke a war between the two countries together with the prince for personal gain. She was afraid that the princess had learned about their plan and was going to tell the king, so the second princess wanted to kill her. The second princess claimed that she had pretended to be a good sister to the eldest princess for so many years, and she was tired of the act. This time, she would not let her go.

The second princess believed that this matter should not be discovered by others, and they needed to find a scapegoat. Zhao Ruoqi came to them, saying that the bracelet was very important to her and she hoped they would return it to her. The second princess asked the national teacher to knock Zhao Ruoqi unconscious and put the knife in her hand, then shouted that Zhao Ruoqi had killed their princess.

The celestial official broke free and injured the national teacher. The national teacher was also very surprised that the celestial official could escape. Both the national teacher and Zhao Ruoqi passed out, and the bracelet returned to Zhao Ruoqi's hand.
